Display apparatus.

摘要

A refresh buffer (2) of a display system stores data to be displayed and phantom attribute bytes which are copies of field attribute bytes. A plurality of phantom attributes bytes each of which controls display condition of corresponding row data are collectively stored in one area (26) of the refresh buffer as a table which is separated from a data area (22) of the refresh buffer. If a display screen is partitioned into left and right viewport, two phantom attribute byte tables are established. Searching, deleting and inserting of data can be performed continuously. So, data handling efficiency is very high.
